LOOWI FOR WEAVING COlR-YARN MATS OR OTHER FAIBRICS.

SPECIFICATION forming part of Letters Patent No. 612,519, dated October18,1898. Application filed December 28, 1897. Serial No. 663,958. (Nomodel.) Patented in E g a d June 5, 894,

To all whom it may concern:

Be it knownthat I, EDWARD HQDDER, av subject of Her Majesty the QueenofGreat Britain, residing at London, England, have invented a certain newand useful Improvement in Looms for Weaving Coir-Yarn Mats or otherSimilar Fabrics, (for which I have obtainedLetters Patent in GreatBritain under date of June 5, 1894, No. 10,940,) of which the followingis a specification.

My invention relates to a certain improvement in looms for Weavingcoir-yarn mats and other similar fabrics; and it consists ofimprovements upon and additions to certain parts of the machine forwhich I have obtained Letters Patent of the United States under date ofNovember 19, 1895, No. 550,174.

. Briefly, my invention relates principally to the means for feeding theyarn for producing the tufts or thrums, to the clip for holding suchyarn during cutting, and to the means for operating and putting out ofoperation said devices. V

I have illustrated my invention in the accompanying drawings, and forthe purpose of more readily comprehending same I have employed a fewletters of reference used in the specification of my prior patent, suchletters being used upon parts which correspond or nearly correspond withthose shown therein. Forthe rest I have generally used numerals todesignate the parts.

In the drawings, Figure 1 is a view of the back end of the loom,sufficient only being shown to illustrate my present improvements. Fig.2 is a partial side view of same, looking from the left-hand side ofFig. 1, the back end being consequently at the right-hand side. Fig. 8is a side elevation showing the means for feeding and holding the tuftor thrum yarn, taken from the opposite side to Fig. 2, the back end ofthe loom being at the lefthand side. Fig. 4 is a side elevation of someof the same parts on an enlarged scale. Fig. 4 is a cro'sssection of thetube through which the yarn is fed, taken on line as at of Fig. 4. Fig.5 is a similar view to Fig. 4, showing the parts in a differentposition. Fig. 6 is a detail of parts shown in Figs. 1 and 2, partly insection and on an enlarged scale. Fig. 7 is a side elevation, partly insection, of the means for lifting the clip which holds the yarn duringcutting; and Fig. 8 is an elevation of same, looking from the right-handside.

According to my presentinvention the yarn 5 5 for forming the tufts orthrums enters the machine (from suitable bobbins) by way of a perforatedbar 1, Figs. 1, 3, 4, and 5, upon which rests a bar 2, having aninverted-U-shaped groove which forms what I term the back clip. The bar2 is guided at its ends by uprights 2. in slots, in which it moves. Thebar 1 is mounted upon a plate 3, extending partly across the machine andcapable of sliding in guides 5, carried by. the inner side frames 6 6.Such plate 3 also supports the. uprights 2. In front of this clip andsecured to the plate 3 are a number of rectangular rear tubes d, one foreach piece of yarn, one end of each of which tubes d slides in a simi-'lar, but larger, forward tube 7, the front end of which slides in afixed guide 8. The rear end of the tube 7 is secured to a plate 9, whichis also supported and can slide in the guides 5, and the two plates 9and 3 are connected at each end bylevers 10 11, which unite and arepivoted on a shaft 10 having rollers 12 at each end working in guides 13on the side frames 6. The levers are adapted to rock on the studs of therollers 12; but the amount they may open is limited by the upper part 13of the guide 13, so thatthey may open to a certain point, but nofarther. The guide 13 at its forward part is depressed, as at 13,

or has an eccentric or cam portion or face for a purpose hereinafterdescribed.

To the plate 3 are attached connecting-rods 1414, pivoted to levers 1515, secured on a shaft (Z extending across between inner side frames 66. On shaft (Z are wheels 61 d, 0 over which pass (as in my priorspecification) chains (1 (1 secured on opposite sides of said Wheels andconnected, respectively, to levers (:1 01 the lever d having a roller (1and the lever d a roller el both levers being piv- 5 oted on a bracket18 and operated by cams (1 and 01 respectively, carried by shaft Ssupported in suitable hearings in the outer side frames 16. "In: thisway, as described in my prior specification, the shaft cl will be werotated in opposite directions alternately as the levers d d are raisedand lowered by the cams, each of which has a depressed surface 17 17,respectively, so that one lever is free to rise when its roller reachessuch depressed surface as the other one is forced down by the plain orlarger diameter of the other, the cams being so arranged that one leverwill be up and the other down alternately. By this reciprocation of theshaft 61 the levers 15, together with the arms 14 and plate 3, will bemoved to and fro. As the plate 3 moves forward the forward plate 9 willalso be moved with it by means of the levers 10 11, the two tubes andplates preserving their relative positions asthey are carried forwarduntil the rollers 12 reach the depressed or cam portion 13 of the guides13, when the lever 10 will dwell, so that the continued forward movementof the plate 3 will cause the lever 11 to close up to lever 10, so thatthe inner tube d is slid into the outer tube 7 until the parts arebrought into the position shown in Fig. 5. During this forward movementthe yarn is held by the back clip as the bar 2 is forced down upon allthe yarns t simultaneously as such yarn passes through the perforatedbar 1, thus gripping same. This movement is effected by the meanshereinafter described. About the end of the bar 2 are lugs 19,projec-ting upwardly and carrying on their ends rollers which work inslots in arms 20 on a shaft 21, carried in the upper side frames F.

This shaft carries at one end a slotted arm 22, Figs. 1 and 2, to whichis pivoted a connectingrod 23, (said rod having play in the slot,)attached at the other end to an arm 24, carrying a roller 25, loose in aslot therein, said arm being pivoted on a stud 26 on the outside of theframe 16. The roller bears on a cam 27, having a gap 28, said cam beingon a shaft 29. The shaft 21, at the opposite end to the arm 22, has anarm 30, to which is attached a spring 31, the other end of which isattached to the outside of the frame. It will be seen that the bar 2 ofthe clip is up while the roller 25 is in contact with the surface of thecam 27, but that when the gap 28 comes opposite the roller the spring 31will rock the shaft 21 by forcing the roller 25 through parts 22 23 24into the gap 28, so that the clip is closed for a comparatively shortperiod, the slot in the arm 24 prolonging the dwell, and is then openedagain as the continued movement of the cam forces the roller 25 out ofthe gap.

In front of the tubes 7 are the knives b and plungers e, the lattercarrying the thrum or tuft formers, the construction and operation ofwhich are fully set out in said prior specification. On the other sideor in front of the thrum-plungers c is what I term the front clip. Thisconsists of a bar 0, (shown in most of the figures, but particularly inFigs. 7 and 8,) such bar being grooved in a similar manner to the bar 2and passing over a bar 32, on the edge of which the ends of the yarns asthey are forced forward are allowed to rest until the clip portion 0descends and holds them all at the same time.

forming part of the thrum-box B. This shaft has a pinion 39, or teethout thereon which gear with the rack 35. At either end are Wheels 40 41.The wheel 41 has a chain 41 affixed to it, as shown in Figs. 2 and6,which passes partly round a pulley 42, carried on a stud on a bar 43.This bar is secured at 44 to a rocking shaft extending across the frameF and capable of rocking therein and carries in addition a roller 45,mounted on a stud. From the pulley 42 the chain passes down partly rounda guide-pulley 46, carried by the frame 16, and thence to the end of alever 47, pivoted on one of the brackets 18, and carrying a roller49,which engages with a cam, 50, secured on the shaft S such cam havinga depression 50, extending a considerable distance round the workingsurface of same andinto which the roller will drop. The shaft 37 alsocarries a boss 37, having a finger 37, against which when in itsperpendicular position the roller of the hanging bar43 bears. There is asimilar arm 43 secured on the shaft 44 on the other side of the frame,and this arm carries the same parts as the arm 43 and engages by roller45 with a similar finger to the finger 37 at the other end of the shaft37. A chain 41 is attached to the wheel 40 of the shaft 37, but passesround same in the opposite direction and from thence over theguide-pulleys 42 46, round which it passes in the same direction, asshown by the dotted line in Fig. 2, and down to a lever 47, pivoted onone of the brackets 18, a roller 49 on said lever engaging with a cam50, such cam having a projection 50 instead of a depression, as theother cam 50 has. The bar 43 has a slot 51, into which projects a pin52, carried by a boss 53 on a rod 54, supported in bearings 55, attachedto the side of the thrum-box B, and in a bearing 56 in the upright 57,which forms part of the heeld-guide.

The rod 54 is jointed to another rod 58, pivoted to a lever 59, rockingon a point 60 on the frame. To a slot in this lever 59 is attached anarm 61, the other end of which is attached to the shaft 21.

It will be seen that the levers 47 47 are alternately moved in oppositedirections by the depression 50 of the cam 50 and the projection 50 ofthe other cam 50, one being pulled down while the other is stationaryand the latter being operated while the first remains stationary, sothat through the chains 41 41, wheels 40 41, pinions 39 39, and racks 35the rods 34 34 are raised and lowered and with themthe front clip 0.

The rollers 45 45 act as stops for the fingers 37, of which there is oneat each end of this shaft 37. WVhen the handle which is provided at theend of the rod 54 is pushed in,

ICS

the pin 52 rocks the bar 43, (and through it the bar 13 and itsconnected parts on the opposite side,) so that the pulleys 42 and 42-lever 59, forcing down the arm 61 in the slot of the lever and rockingthe shaft 21, which raises the arm 22 and clips 2 and with it theconnecting-rod 23, which acts to raise the arm 24;, thus keeping theroller out of the gap 28 of the cam 27. In this way the motion of theback or feeding clip 0 is stopped, so that the tuft or thrum yarn ceasesto be fed and the. pile to be woven; but as the warp y, Fig. 3, is notinterfered with and the shuttle still. carries the weft across it aplain fabric is produced, (which forms a division between the pilefabric or mat,) which will continue to be made so long as the rod 54 isin that position.

S is the main shaft of the machine, and motion is imparted from it tothe shaft S by the aid of the pinion 63, which gears into a pinion 64 onsaid shaft S, a farther pinion 65 on said shaft gearing with a pinion 66on shaft S which pinion G6 gears with a pinion 67 on shaft S a pinion68, also on said shaft S driving a pinion 69 of the shaft 29.

In the general operation of the machine as far as the present inventionis concerned it will be seen that the tuft or thrum yarn is held in theperforations of the bar 1 by the downward movement of the clip-bar 2 produced by the rockingpf the shaft 21 and that as the arm 14 is forcedforward by the forward rocking movement of the shaft al the plate 3 andclip are moved forward, the roller carried by the lugs 19 of the clipmoving in the slot in the arm 20. The movement of the clip draws theyarn off the bobbins and at the same time forces forward the inner tubesd, together with the tubes 7 and plate 9, until such tubes 7 are withina very slight distance of the knife I), the position being shown in Fig.5. At this point the roller 12 falls .into the depression 13 oftheguides 13, so that the movement of the parts 10, 9, and 7 are stopped;but the motion of the arm is being continued the tubes cl close up intothe position shown in Fig. 5, pushing forward the yarns out of tubes 7over the bar 32 of the front clip, which is then operated and broughtinto the position shown in Fig. 5. The yarns being now held, the knifeI) descends and cuts off a length of each, after which the bar 0 of theclip is raised to release them to enable them to be operated on by thethrum-formers e. The back clip 2 is then raised by its operating parts.The plate 3, the clip, and the tubes d are withdrawn, the yarn passingfreely into the tubes d in the backward movement of the latter until theroller 12 is out of this depression 13, when the levers 1O 11 again movetogether a short distance back, (by

means of the part 13 which prevents them opening farther,) withdrawingthe tubes 7,

after which the clip 2 comes down again, and

the parts are in the position shown in Fig. 4 and ready for the nextfeeding movement.

hat I claim is- 1. In a loom for weaving coir-yarn mats and othersimilar fabrics and in combination, a rear tube, a forward tube in whichthe rear tube is capable of sliding and means for moving said rear tubeand forward tube together for a certain distance, and then stopping theforward tube and moving the rear tube only to protrude the yarn from theformer,sub-

' stantially as described.

2. In a loom for weaving coir-yarn mats and other similar fabrics and incombination, a rear and a forward tube for carrying the tuft or thrumyarn, means for moving same independently for portions of theirmovement, and together for other portions, and means for holding downthe yarn and releasing it at intervals, such means moving with the reartube, substantially as described.

' 3. In a loom for weaving coir-yarn mats and other similar fabrics andin combination, a bar 1 having a series of holes for the tuftyarn topass through, a bar 2 havinga groove adapted to receive the bar 1,guides for the bar 2, and means for raising and lowering the said bar 2to nip all the yarns on the bar 1 simultaneously substantially asdescribed.
